Embodiment 1

[0011] A green and environment-friendly water-based release agent is characterized in that it comprises the following raw materials in parts by weight: 5 parts of paraffin, 5 parts of stearic acid, 5 parts of vegetable oil, 5 parts of co-emulsifier, 2 parts of potassium hydroxide, Parkin ethyl ester 0.5 parts, deionized water 80 parts.

[0012] The beneficial effects of the present invention are: the formula of the present invention is simple and practical, and the raw materials are pure green and environment-friendly. In addition, the water-based release agent of the present invention can not only play a lubricating role at high temperature, but also prevent the liquid metal from affecting the surface of the cavity. The scouring effect of the mold improves the working conditions of the mold, prevents the mold from sticking, reduces the thermal conductivity and mold temperature of the mold, and adjusts the temperature of each part of the mold to achieve a relatively stable temp...

Embodiment 2

[0014] A green and environment-friendly water-based release agent is characterized in that it comprises the following raw materials in parts by weight: 20 parts of paraffin, 8 parts of stearic acid, 10 parts of vegetable oil, 8 parts of co-emulsifier, 3 parts of potassium hydroxide, and Parkin ethyl ester 1 part, deionized water 100 parts.

[0015] The beneficial effects of the present invention are: the formula of the present invention is simple and practical, and the raw materials are pure green and environment-friendly. In addition, the water-based release agent of the present invention can not only play a lubricating role at high temperature, but also prevent the liquid metal from affecting the surface of the cavity. The scouring effect of the mold improves the working conditions of the mold, prevents the mold from sticking, reduces the thermal conductivity and mold temperature of the mold, and adjusts the temperature of each part of the mold to achieve a relatively stable ...

Embodiment 3

[0017] A green and environment-friendly water-based release agent is characterized in that it comprises the following raw materials in parts by weight: 12.5 parts of paraffin, 6.5 parts of stearic acid, 7.5 parts of vegetable oil, 6.5 parts of co-emulsifier, 2.5 parts of potassium hydroxide, and Parkin ethyl ester 0.75 parts, deionized water 90 parts.

[0018] The beneficial effects of the present invention are: the formula of the present invention is simple and practical, and the raw materials are pure green and environment-friendly. In addition, the water-based release agent of the present invention can not only play a lubricating role at high temperature, but also prevent the liquid metal from affecting the surface of the cavity.

Abstract

A disclosed green environment-friendly water-base mold release agent is characterized by comprising the following raw materials in parts by weight: 5-20 parts of paraffin, 5-8 parts of stearic acid, 5-10 parts of plant oil, 5-8 parts of a co-emulsifier, 2-3 parts of potassium hydroxide, 0.5-1 parts of ethylparaben, and 80-100 parts of deionized water. The mold release agent is simple and practical in formula, and pure green and environment-friendly in raw materials. Additionally, the water-base mold release agent gives play to lubrication effect at a high temperature, also avoids washing effect of a metal liquid on a cavity surface, helps to improve working conditions of a mold, and is capable of avoiding sticking to the mold, reducing the thermal conductivity of the mold and mold temperature, and adjusting the temperature of all parts of the mold to reach a relatively stable state, so that the formability is improved, and a formed film is capable of reducing friction and wearing between a casting and the mold cavity and especially the core, and prolonging the service life of the mold.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a green and environment-friendly water-based release agent. Background technique [0002] The mold release agent (mold discharging agent) is a functional substance between the mold and the finished product. Mold release agents are chemically resistant and do not dissolve when in contact with the chemical composition of different resins (especially styrene and amines). The release agent also has heat and stress resistance, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the workpiece to be processed, and does not hinder painting or other secondary processing operations. Due to the rapid development of injection molding, extrusion, calendering, molding, lamination and other processes, the amount of release agent has also increased significantly. Most of the existing general release agents are not environmentally friendly, and ...
